WATCH-MAKERS TOOL.V

` SPECIFICATION forming part of Letters Patent No. 252,222, dated January Application filed December 3, 1881. (No model) To all whom yit may concern:

Beit known that I, GEORGE W. J oENsoN, of Newton, in the county of Jasper and State of Illinois, have invented a new and Improved Watch-Makers Tool, of which the following'is a full, clear, and exact description.

My invention consists of a pineher-shaped toolorimplement for removing rollers from the balancewheel posts of watch-movements, one of the jaws ofthe tool being flattened and divided to forni fingers or tines adapted tobe passed between the balance-wheel and the roller, straddle of the post, the otherjaw be-l ing formed with a passage, perforation, orrecess for4 the reception of the pivot Oi' the post, so that the end of the jaw will rest upon the shoulder of the post where power is applied to the handles ofthe tool for forcing off the roller.

Reference is to be had to the accompanying draw-ings,fornii11g part of this specitcation,

` in which similar letters of' reference indicate cozresponding parts in both the figures.

Figure l is a sectional side elevation of my invention as it appears when' applied for removing a roller; and Fig. 2 is a. 'sectional plan view of the same, taken on the line m x, Fig. l.

The jaw a of' the tool or iniplenientA is flat.-

` tened at the end and divided to form the finpass between the wheel and the circular plate or roller c, as clearly shown in Fig. l. .f

The jaw b of the tool or implement is pret'- erably curved over, as shown, and the end ot' it is formed with the hole or recess i, which is of suitable size and depth to receive the pivot o ofthe post, so that the end of the jaw will rest upon the shoulderj ot the post, (which is formed by reducing the same to forni the pivot.) which furnishes a solid support for the jaw when power is applied tothe handles ofthe tool or implement for forcing the roller off from the post. t

By means of this tool the rollers or circular plates may be quickly and easily removed from the post withont'dauger of breaking the roller or bending or otherwise injuring the post or the pivots thereof. Having thus described my invention, I claim as new and desire to secure by Letters Patent- The tool herein shown and described, consisting of the jaws ot and b, the jaw a being flattened and divided to form the lingers Or lines c c, the jaw b being-termed with therecess e, substantially as and for the purposes set forth. l
